COMPAC GEN II HEAT/COOL IMPORTANT NOTICE-PLEASE READ FOR MAXIMUM SYSTEM PERFORMANCE VINTAGE AIR RECOMMENDS THE FOLLOWING: THIS KIT DOES NOT CONTAIN HEATER HOSE. YOU MUST PURCHASE 8 FEET OF 5/8" DIA. HEATER HOSE FROM VINTAGE AIR (3800-VUD) OR FROM YOUR LOCAL PARTS RETAILER. SAFETY SWITCHES: A COMPRESSOR SAFETY SWITCH MUST BE INSTALLED ON EVERY A/C SYSTEM. A BINARY SWITCH (PART# 24679-VUS) DISENGAGES THE COMPRESSOR CLUTCH IN CASE OF EXTREME LOW PRESSURE CONDITIONS (REFRIGERANT LOSS) OR EXCESSIVELY HIGH HEAD PRESSURE (406 PSI.) TO PREVENT COMPRESSOR DAMAGE OR HOSE RUPTURE. A TRINARY SWITCH (PART# 24678-VUS) COMBINES HI/LOW PRESSURE PROTECTION WITH AN ELECTRIC FAN OPERATION SIGNAL AT 254 PSI. COMPRESSOR SAFETY SWITCHES ARE EXTREMELY IMPORTANT SINCE AN A/C SYSTEM RELIES ON REFRIGERANT TO CARRY LUBRICATION THROUGH THE SYSTEM. SERVICE INFO: ATTENTION: SYSTEM COMPONENTS: THE COMPRESSOR, EVAPORATOR, CONDENSER & DRIER ARE CAPPED. CAPS MAY BE UNDER PRESSURE WITH DRY NITROGEN. BE CAREFUL REMOVING CAPS. DO NOT REMOVE CAPS PRIOR TO INSTALLATION. REMOVING CAPS PRIOR TO INSTALLATION WILL CAUSE COMPONENTS TO COLLECT MOISTURE AND LEAD TO PREMATURE FAILURE AND REDUCED PERFORMANCE. EVACUATE THE SYSTEM FOR 35-45 MINUTES WITH SYSTEM COMPONENTS (DRIER, COMPRESSOR, EVAPORATOR, AND CONDENSER) AT A TEMPERATURE OF AT LEAST 85 F. ON A COOL DAY. THE COMPONENTS CAN BE HEATED WITH A HEAT GUN OR BY RUNNING THE ENGINE WITH THE HEATER ON BEFORE EVACUATING. LEAK CHECK AND CHARGE TO SPECIFICATIONS. VINTAGE AIR SYSTEMS ARE DESIGNED TO OPERATE WITH R34a REFRIGERANT ONLY! USE OF ANY OTHER REFRIGERANTS IS A FIRE HAZARD AND COULD DAMAGE EITHER YOUR AIR CONDITIONING SYSTEM OR YOUR VEHICLE. USE OF ANY OTHER REFRIGERANTS WILL VOID ALL WARRANTIES OF THE AIR CONDITIONING SYSTEM AND COMPONENTS. USE OF THE PROPER TYPE AND AMOUNT OF REFRIGERANT IS CRITICAL TO PROPER SYSTEM OPERATION. VINTAGE AIR RECOMMENDS OUR SYSTEMS BE CHARGED BY WEIGHT WITH A QUALITY CHARGING STATION OR SCALE. REFRIGERANT CAPACITIES FOR VINTAGE AIR SYSTEMS (FOR OTHER SYSTEMS, CONSULT MANUFACTURER GUIDELINES) R34a SYSTEM CHARGE WITH.8 lbs. ( lbs. 2 oz) OF REFRIGERANT LUBRICANT CAPACITIES: NEW COMPRESSOR - NO ADDITIONAL OIL NEEDED USED COMPRESSOR - CONSULT VINTAGE AIR 90680-VUX-A REV E 2/28/4, INST. GEN II COMPAC HC PG 4 OF 4 4
PLANNING OVERVIEW EVERY VEHICLE IS A LITTLE DIFFERENT, DEPENDING ON THE:. TYPE OF VEHICLE/ENGINE AND LOCATION OF ENGINE. 2. TYPE OF AIR CONDITIONING EQUIPMENT USED. 3. OWNER'S PREFERENCES. THERE ARE MANY FACTORS THAT GO INTO MAKING EACH AIR CONDITIONING INSTALLATION DIFFERENT. USUALLY, ALL OF THE ABOVE DECISIONS ARE MADE BEFORE ANY CONSIDERATION IS GIVEN TO THE AIR CONDITIONING INSTALLATION. THE A/C SYSTEM IS THEN TAILORED TO FIT YOUR PARTICULAR APPLICATION. THE MOUNTING LOCATION OF THE EVAPORATOR UNIT IS DETERMINED IN PART BY THE SPACE AVAILABLE FOR THE HOSE ROUTING. THE COMPONENTS USED IN THE HOSE ROUTING PROCESS (I.E. BULKHEAD PLATES, FITTINGS, AND GROMMETS, ETC.) WILL ALSO INFLUENCE THE LOCATION OF THE EVAPORATOR UNIT. WHEN PLANNING YOUR HOSE ROUTING, YOU MUST INSTALL THE MAJOR COMPONENT PARTS. MOUNT THE COMPRESSOR, CONDENSER, AND DRIER. THE EVAPORATOR MUST BE TEMPORARILY HELD IN POSITION UNDER THE DASH. FINAL MOUNTING OF THE EVAPORATOR TO THE FIREWALL SHOULD NOT BE DONE, UNTIL YOU HAVE VERIFIED THAT ALL HOSES ATTACHING TO THE EVAPORATOR WILL EXIT THE FIREWALL AND/OR KICK PANEL AS PLANNED. THE HOSES MUST BE RUN EXACTLY THE WAY THEY WILL BE WHEN FINISHED, BEFORE CUTTING THEM TO LENGTH. DUCT HOSE ROUTING AND A/C VENT LOCATIONS SHOULD ALSO BE GIVEN CAREFUL CONSIDERATION BEFORE FINAL MOUNTING POSITION OF THE EVAPORATOR IS SELECTED. THE VINTAGE AIR GEN II COMPAC UNIT WAS DESIGNED FOR STREET RODS, CUSTOM CARS, AND TRUCKS. THE EVAPORATOR UNIT IS DESIGNED TO MOUNT BEHIND THE DASH. READ THE INSTALLATION INSTRUCTIONS COMPLETELY, AND FAMILIARIZE YOURSELF WITH ALL THE PARTS AND ILLUSTRATIONS. THE INSTALLATION OF THIS UNIT VARIES, ACCORDING TO THE BODY MANUFACTURER OR MODIFICATIONS TO THE ORIGINAL BODY. THE COWL VENT MAY REMAIN OPERATIONAL. TAKE YOUR TIME, AND DOUBLE CHECK BEFORE DRILLING OR CUTTING. BEFORE BEGINNING, REMOVE COWL VENT HANDLE AND GLOVE BOX TO EASE INSTALLATION. IF THE DASH IS EASILY REMOVABLE, REMOVE IT NOW. CHECK FOR, AND FILL IN ANY HOLES IN THE FIREWALL AND FLOOR. INSULATE AND SEAL FIREWALL, FLOOR, DOOR PANELS, AND HEADLINER TO REDUCE THE AMOUNT OF HEAT ENTERING THE CAR. FIGURE SHOWS THE GENERAL LOCATION OF THE EVAPORATOR. LOCATIONS WILL VARY. 5 FIGURE 90680-VUX-A REV E 2/28/4, INST. GEN II COMPAC HC PG 5 OF 4
INSTALLATION STEPS. MOUNT COMPRESSOR ON ENGINE. FOLLOW THE INSTRUCTIONS INCLUDED WITH COMPRESSOR BRACKET KIT. 2. MOUNT CONDENSER IN PROPER LOCATION. 3. BRACKETS ARE FURNISHED TO MOUNT THE EVAPORATOR CASE. ATTACH TO FIREWALL AS SHOWN IN FIGURE 2. 4. THE COWL VENT HANDLE WILL WORK IF MOVED TO THE SIDE. YOU CAN ALSO CONVERT TO ELECTRIC OR CABLE OPERATION. IF YOU CLOSE THE COWL VENT, THE UNIT WILL FIT HIGHER IN THE CAR. NOTE: TO MOUNT UNIT HIGHER, SIMPLY DETERMINE THE NEW LOCATION, MARK AND RE-DRILL THE BRACKET TO FIT AS DESCRIBED IN STEP 6 - FIGURE 2. DASH MOUNT HEADER 5. WHEN FITTING THE EVAPORATOR: A. REMOVE BLOWER MOTOR COVER. B. ATTACH REAR BRACKET TO THE EVAPORATOR, USING (2) /4-20 x /2" BOLTS. C. TEST FIT REFRIGERATION FITTINGS WITH HOSES FOR PROPER CLEARANCE INSIDE THE CAR. REFER TO HOSE ROUTING INSTRUCTIONS ON PAGE 8. DRILL THREE (3) FIGURE 2 9/32" HOLES 6. HAVE A HELPER HOLD THE UNIT UP AS HIGH AS POSSIBLE, WITH BLOWER HOUSING AGAINST PASSENGER SIDE KICK PANEL. LOCATE THE BRACKET ON THE TOP RIGHT OF THE BLOWER HOUSING. SCRIBE THRU THE /4" HOLE IN THE BRACKET TO MARK THE FIREWALL. CHECK TO SEE IF THE LOCATION YOU MARKED LOOKS CORRECT AND WILL CLEAR OBSTRUCTIONS ON BOTH SIDES OF THE FIREWALL. IF SO, DRILL A 9/32" HOLE IN THE FIREWALL. ATTACH THE EVAPORATOR TO THE FIREWALL BY THE BLOWER MOTOR BRACKET WITH A /4-20 x " BOLT AND NUT. LEVEL THE EVAPORATOR UNIT, AND USE THE /4" HOLE IN THE BRACKET TO THE FIREWALL WITH A /4-20 x " BOLT. THIS WILL LOCATE THE EVAPORATOR HORIZONTALLY. NOW SECURE THE FRONT EVAPORATOR SUPPORT STRAP TO THE UNIT WITH THE SUPPLIED /4-20 x /2" BOLT. THIS SUPPORT BRACKET WILL ATTACH TO THE DASH MOUNT HEADER. WITH THE UNIT HELD IN PLACE (PLUMB AND LEVEL), MARK THRU THE /4" HOLE AT THE TOP OF THE BRACKET TO THE SHEET METAL HEADER. MAKE SURE THAT THE SPOT MARKED WILL PROVIDE A GOOD MOUNTING LOCATION FOR THIS BRACKET. DRILL 9/32" MOUNTING HOLE. SECURE THE MOUNT STRAP TO THE COWL HEADER AS SHOWN IN FIGURE 2 WITH A /4-20 x " BOLT AND NUT. 90680-VUX-A REV E 2/28/4, INST. GEN II COMPAC HC PG 6 OF 4 6
A/C LINES & FITTINGS INSTALLATION 7. PUSH THE 5/6" I.D. HOSE ONTO THE STRAIGHT #6 FITTING. (SEE HOSE ROUTING ILLUSTRATION ON PG. 8). INSTALL THE FITTING ONTO THE EXPANSION VALVE (FINGER TIGHT). PUSH THE /2" I.D. HOSE ONTO THE STRAIGHT #0, AND INSTALL THE FITTING ONTO THE #0 LINE ON THE EVAPORTOR. (SEE HOSE ROUTING ILLUSTRATION PG. 8). 8. AT THIS TIME, TRY TO DETERMINE WHERE YOU WANT YOUR LINES TO GO THRU THE FIREWALL. MOVE THE HOSES TO THAT POINT. HOLD THE FITTINGS UP TO THEIR RESPECTIVE HOSES, AND DETERMINE IF THE HOSES WILL CONFORM TO THE LOCATION FOR THE BULKHEAD FITTINGS OR OPTIONAL BULKHEAD PLATE (VINTAGE AIR PART# 3425-VUQ OR 3428-VUQ). THE /2" HOSE IS HARD TO BEND AT A SHARP ANGLE, AND THE FITTINGS TAKE UP A CERTAIN AMOUNT OF SPACE. BEFORE YOU DRILL HOLES IN YOUR FIREWALL, MAKE SURE THAT YOU CAN MAKE THE HOSES FIT WHERE YOU HAVE PLANNED. THE ENGINE COMPARTMENT APPEARANCE IS A CONSIDERATION WHEN CHOOSING THIS LOCATION. 9. WHEN YOU HAVE DECIDED WHERE YOU WANT TO PLACE YOUR BULKHEAD FITTINGS, MARK THESE POINTS WITH A GREASE PENCIL, AND MARK A TEMPLATE FROM THE INSIDE OF LOCATING WHERE THE HOLES WILL BE CUT. WITH THIS TEMPLATE, LOCATE THE SAME POINTS ON THE OUTSIDE OF THE FIREWALL. MARK THESE POINTS WITH A GREASE PENCIL. 0. DETERMINE THE BEST LOCATION FOR THE DRIER THAT WILL ALLOW ADEQUATE ROOM FOR THE HOSE AND FITTINGS THAT CONNECT THE DRIER TO THE BULKHEAD FITTING.. MOUNT THE DRIER. (KEEP THE DRIER CAPPED AS MUCH AS POSSIBLE, IF YOU MUST SCREW THE FITTING TO THE DRIER, TAPE IT CLOSED). NOTE: THE DRIER IS USUALLY MOUNTED WHERE YOU HAVE ROOM FOR IT. JUST REMEMBER TO MOUNT IT IN THE COOLEST SPOT POSSIBLE AND VERTICALLY SO THE SIGHT GLASS IS DIRECTLY ON TOP. (NOT NEXT TO THE EXHAUST MANIFOLD). IT CAN BE MOUNTED INSIDE THE VEHICLE AS WELL. 2. AT THIS POINT, CUT HOLES FOR BULKHEAD FITTINGS, AND INSTALL THEM. 3. USING THE HOSE ROUTING ILLUSTRATION ON PG. 8 AS A GUIDE, ROUTE REMAINING A/C LINES, AND CUT TO LENGTH. 4. INSTALL A/C VENTS THAT WILL BE USED AT THIS TIME. 5. CENTER OUTLET: YOU MAY USE THE CENTER PANEL FURNISHED, OR YOU CAN MOUNT THE VENTS IN DASH. IF YOU USE THE CONTROL PANEL, THE TOP MOUNTING LIP SHOULD BE BACK /4" x /2" FROM LOWER LEADING EDGE OF DASH. LOCATE THE 2 /2" I.D. HOSE, AND ROUTE FROM THE DASH VENTS TO THE EVAPORATOR. 6. AT THIS TIME, YOU SHOULD HAVE THE REFRIGERATION HOSES CUT TO THEIR PROPER LENGTH. PAY CLOSE ATTENTION TO THE ORIENTATION OF ANY HOSE WITH TWO ANGLED FITTINGS. ANY HOSE WITH TWO ANGLED FITTINGS MUST BE MARKED FROM THE HOSE TO THE FITTINGS TO ASSURE THEY WILL REMAIN IN THIS POSITION AFTER CRIMPING. THE RUBBER HOSE IS ONLY CAPABLE OF A MINIMAL AMOUNT OF TWIST TO AID ALIGNMENT. 7. REMOVE HOSES AND CRIMP ENDS. IF YOU DO NOT HAVE ACCESS TO THE PROPER EQUIPMENT, YOU MUST TAKE THEM TO A QUALIFIED A/C SERVICE CENTER FOR CRIMPING. (SEE CRIMPING INSTRUCTIONS SUPPLIED WITH THE HOSE KIT). 8. WITH THE EVAPORATOR TRIAL FIT COMPLETE, YOU MAY REMOVE UNIT AND LOWER IN VEHICLE. 9. AFTER CRIMPING HOSES, LOCATE THE #6 A/C HOSE WITH THE STRAIGHT FITTING. LUBRICATE A #6 A/C O-RING AND THE THREADS ON THE FITTINGS, AND INSTALL ON THE EXPANSION VALVE. TIGHTEN CAREFULLY. REFER TO FIGURES 3 & 3A, PAGE 9. 20. LOCATE THE #0 A/C HOSE WITH THE STRAIGHT FITTING. LUBRICATE A #0 O-RING AND THE THREADS ON THE FITTING, AND INSTALL ON THE #0 LINE OF THE EVAPORATOR. TIGHTEN CAREFULLY.
